concavities correspond to the diameters of the open ends of the tubularknuckle, the concavities of the caps being in opposition to the openends of the tubular knuckle when the parts of the hinge are assembled,as shown.

In order to pivotally connect the complemental members and 11 as well asserving as bearings whereby the members of the hinge may be guided toand from each other when-the door is swung accordingly, in the open endsof the tubular knuckle 15 of the complemental member 10 are two pivotingelements, as 19 and 20, both of which may be similarly formed. Eachofthe pivoting elements 19 and 20 may be substantially spherical, orball-shaped,-though the oppos ing parts of the elements may also becutaway, as at 21 and 22. The spherical pivoting elements 19 and 20 areless in diameters than the diameters of the tubular knuckle 15 and theconcavities of the caps 17 and 18 to allow these elements to revolvetherein, and these elements are arranged in the tubular knuckle forpartially protruding normally therefrom so that the protruding ends willbe seated in the caps 17 and 18.

Serving to yieldingly retain part of the pivoting elements 19 and 20 inthe concavities of the caps 17 and 18, interiorly of the tubular knuckle15 of the complemental member 10 of the hinge, is a cushion, as 23. Thecushion 23 is preferably in the form of a spiral spring having its endscontacting with the cutaway. parts 21 and 22 of the spherical, orball-shaped pivoting elements, and this spring is of a tension so as tonormally tend to force these pivoting elements outwardly of the tubularknuckle into the caps 17 and 18 of the complemental member 11. appliedtoa door andits frame, the complemental members 10 and 11 may beseparated by forcing the members apart, the

cushioned ball-shaped pivoting elements and the concavities of the caps17 and 18 per-' mitting the separation to be easily made. The leaf ofthe complemental member ,10 may be secured to the frame of the door,while the leaf of the complemental member 11 may be mounted on the door.These members are then connected by forcing the caps 17 and 18 over theball-shaped pivoting elements 19-and 20, and the door will be hung inits frame so as to be swung to open and closed positions. Moreover, byproviding the ball-shaped pivoting elements and the concaved capssurface bearings are formed for the complemental members wherebyfrictional wear of these parts will be largely overcome, and the use ofapertured lugs and a pintle common to the ordinary types of h nged doorsmay be dispensed with.

When the hinge is In the foregoing description, 1 have em- 1 bodied thepreferred form of my invention, but I do not wish to be understood aslimit ing myself thereto, as I am aware that modifications may be madetherein without departing from the principle, or sacrificing any of theadvantages of this invention, therefore I reserve to myself the right tomake such changes as fairly fall within the scope thereof. l

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1.' A hinge comprising two complemental members, atubular knuckle on one of said members, and two spaced concave plates onthe other of said members, said plates being so disposed that theconcavities therein are in opposed relation and adapted to accommodatethe tubular knuckle therebetween; together with a pivoting elementmounted in said tubular knuckle and having parts protruding therefrominto and engaging the concaved plates for yieldingly retaining saidcomplemental members in cooperative relation to each other,substantially as described.
